While Memorial Day weekend marks the start of summer fun, for the family and friends of Sean Kingston the weekend has been marred by tragedy.

According to TMZ, the singer was critically injured in a jet-ski accident last night. The website says that Sean and a female passenger riding the vehicle crashed into a bridge around 6 PM last night. They were rescued and brought to shore by a good Samaritan and rushed to the hospital after Miami Fire Department arrived. He is currently being treated in the hospital’s trauma ward for severe injuries.

In a statement, Sean’s rep said:

“Sean Kingston was in an accident today. No further details are available at the moment. He and his family thank everyone for the well-wishes.”

Stars including Rihanna, Nicki Minaj and LL Cool J have taken to Twitter to send their well wishes for the “Beautiful Girls” singer.
